Patent DE-3802100-A1 (DE)
Title: Arrangement with a switch, mounted on the wheel of a motor vehicle, for monitoring the internal pressure of a tyre
Inventor: WEIBLER WOLFGANG DR
IPC: G08C17/04
Filed: 1988-01-26
Abstract: The invention relates to an arrangement for monitoring a status variable in the interior of the wheel of a motor vehicle, which variable is emitted by one of the positions of a switch mounted there as long as the said position is within a desired range. When the position leaves this range, the switch assumes the other position which is inductively interrogated once per revolution of the wheel by a pulse transmitter mounted on the chassis by an oscillatory circuit mounted on the wheel being excited to produce damped oscillations whose degree of damping is determined by the switch position. This degree of damping is tapped off at least once in a fixed time interval after excitation at the damped oscillation received by the circuit of the chassis and is tested in an evaluation device, the position of the switch in the interior of the tyre being determined as a function of the size of the said damping and, if appropriate, a warning device for the driver being activated. The entire arrangement operates in the kilohertz range and can thus be easily realised by commercially available circuitry components. <IMAGE>
Patent DE-3802452-A1 (DE)
Inventor: UTHEMANN HORST DIPL CHEM DR
IPC: G01N33/80
Filed: 1988-01-28
Abstract: A method for determining blood groups by the solid-phase method using blood group-specific antibodies and a carrier to whose surface the antibodies can be irreversibly bound is obtained by a solution of an antibody of the IgM type
 (a) either being contacted with the carrier surface simultaneously with the erythrocyte suspension to be determined or
 (b) the antibodies first being dried as reagent reservoir on the carrier surface and being dissolved, and thus contacted with the carrier surface, only by the addition of the erythrocyte suspension when the assay is carried out,
 and the determination being carried out a short time after the contacting, it being necessary that the antibody concentration is no higher than required to form an irreversible or immobilised layer of antibody molecules on the carrier surface, which layer is able specifically to bind erythrocytes, and is insufficient to bring about an agglutination reaction.
Patent DE-3813288-A1 (DE)
Title: Method and water-heating installation for water heating
Inventor: BAUER JOSEF
IPC: F24D17/00
Filed: 1988-04-20
Abstract: Until now, water-heating installations have worked by admixing cold water to the hot water heated to a given temperature, in order to be able to have available at a withdrawal point mixed water with a lower temperature. By admixing cold water, there is the danger that legionellae may multiply greatly in the mixed water of medium temperature. Even the water of low temperature to be admixed to the hot water heated to the given temperature is obtained from the hot water of a given temperature by cooling by means of heat exchange, so that even the water to be admixed is free from legionellae. In this heat exchange, the cold water supplied is, at the same time, raised to a medium temperature. The method and water-heating system is to be used in installations of all sizes, but preferably in large installations such as swimming baths and hospitals. <IMAGE>
Patent DE-3813799-A1 (DE)
Title: Scraper chain for central chain scraper conveyors
Inventor: THIELE ALFRED DIPL ING
IPC: B65G19/20
Filed: 1988-04-23
Abstract: Particular difficulties arise when running through the curves in double central chain scraper conveyors as a result of the fact that in the curve region the chain strand sections situated radially further out must take up the drawing force in the chain belt virtually alone, while the chain strand sections situated radially further in pass through the curve region hanging more or less loosely. The said difficulties are avoided using a scraper chain which is composed alternately of vertically arranged sectional or round steel links and forged links arranged horizontally between the said sectional or round steel links and has scrapers on individual forged links, in that at least those forged links (4) provided with scrapers (6) are constructed so as to be plate-like and have a horizontal circular-arcuate cutout (7), which is symmetrical with respect to the longitudinal extent of the scraper chain (1), as a swivelling segment for vertical links which engage in the cutout (7). The shaft effect achieved in this manner when running through the curves in particular of roller curve conveyors can at the same time be further improved in that on that side, situated opposite the circular-arcuate cutout (7) in the conveying direction (8), of the horizontal forged link (4) there is provided an elongate hole (11) for the engagement of vertical links (2, 3 or 2a, 3a), the elongate hole (11) on the forged link (4) likewise being arranged on the swivelling circle (12) formed by the circular-arcuate cutout (7). <IMAGE>

Patent DE-3818508-A1 (DE)
Title: Sterilisable model of an eccentric screw pump
Inventor: HANTSCHK GUENTHER
IPC: B08B9/032
Filed: 1988-05-31
Abstract: The main components of the pump are a stator (22) in which there is eccentrically and rotatably arranged a rotor (26), a drive shaft casing (10) in which there is arranged a drive shaft (12), an intermediate shaft casing (18) in which there is arranged an intermediate shaft (20) connecting the rotor (26) to the drive shaft (12) and the end casing (32) on that end of the stator (22) which faces away from the intermediate shaft (20). On the intermediate shaft casing (18) there are arranged, in the vicinity of the drive shaft casing (10), a first connection nozzle (42) and a second connection nozzle (44) in the vicinity of the stator (22). A third and fourth connection nozzle (46, 48) are arranged on the end casing (32) and are connected to one another by means of a bypass pipe (50) which contains at least one shut-off valve (52). The first and second connection nozzles (42, 44) are arranged at least approximately tangentially to the intermediate shaft casing (18) in such a way that a liquid which emerges through one of these two connection nozzles (42, 44) into the intermediate shaft casing (18) has a swell imparted to it and emerges in the direction of rotation of the said swell through the other one of these two connection pieces (44, 42). During cleaning in accordance with the CIP method, the swell ensures that the cleaning liquid even reaches those parts which have up to now been particularly difficult to clean. <IMAGE>
Patent DE-3821817-A1 (DE)
Title: Spraying apparatus and method for controlling the latter
Inventor: FORSTER KLAUS
IPC: B05B7/12
Filed: 1988-06-29
Abstract: The invention relates to spraying apparatuses in which a free-flowing material and a gas under pressure pass out of a spraying head (11) for the purpose of atomised application of the material to an article. In known apparatuses of this type, the start and the termination of the material feed and gas feed occur in each case simultaneously. This has the disadvantage at the finish of the spraying that complete atomisation does not take place and small residual material particles remain adhering to the nozzle (12) and dry hard on the latter. The invention is to avoid these disadvantages. The invention provides a spraying apparatus in which the gas outlet can be closed with a temporal delay after the material outlet. Furthermore, the invention relates to a method for the corresponding control of the spraying apparatus, in that the material feed and gas feed are indeed released simultaneously but an annular channel (13) for the passing out of the gas is closed only after closing of the nozzle (12) for passing out of the material. The spraying apparatus according to the invention is particularly suitable for applying atomised lacquers (paints), adhesives or oils to an article. <IMAGE>

Title: Lever drive for wheelchairs
Inventor: OLBRICH GERHARD
IPC: A61G5/02
Filed: 1988-07-19
Abstract: In known lever drives, the drive can only be interrupted if the drive lever (1) is released and the adjustment at the connecting rod (2) is opened. The drive mechanism (3) turns continuously on pushing of the wheelchair. The new drive is displaced in fresh air by shifting the selection lever (4). By shifting the braking lever (6) the wheelchair is braked, in a metered manner if desired. In free running, the connection between the drive mechanism (3) and the drive wheel (6) is interrupted. On rolling of the wheelchair the drive lever (1), the connecting rod (2) and the drive mechanism (3) are at a standstill. This construction permits shifting of the gear and braking without removing the hand from the drive lever. On standstill in the blind angle (A or B) a new drive angle is chosen by shifting with the selection lever (4). The drive is suitable for wheelchairs with one-armed or two-armed operation. <IMAGE>
Patent DE-3830071-A1 (DE)
Title: Device for connecting and fixing two pivoting parts
Inventor: KUNDE DETLEV DIPL ING
IPC: A01F12/40
Filed: 1988-09-03
Abstract: A device (10) for fixing and connecting two pivoting parts (12, 14), especially of a chopper and a spreading cowl on a combine harvester, one of which is pivotable about a bearing (24) on a frame (16) and can be connected to the frame (16) via a locking element (20), is to be designed in such a way that the two pivoting parts (12, 14) can be brought into their operating position and held in this by few fastening means. For this purpose, the first pivoting part (12) is initially pivoted into its operating position and is held there temporarily by means of a locking element (20). The second pivoting part (14) is subsequently pivoted permanently into the path of movement of the other, and the locking element (20) is connected not to the frame (16) but instead to the other pivoting part (14), so that these can no longer move away from one another. Devices of this type are used on choppers or the like which are mounted on a combine harvester. <IMAGE>
Patent DE-3832540-A1 (DE)
Title: Pressing machine or laundry mangle with a foot switch
IPC: F16P3/18
Filed: 1988-09-24
Abstract: In a pressing machine or laundry mangle with a motor-operated roller and a heated bowl which, by the actuation of a function switch, for example a foot switch, connected operatively to a control device, can be pressed against the roller and can be lifted off from the latter to a predetermined safety distance for the purpose of smoothing the pressing material or inserting it between the bowl and roller, the control device also has, in addition to the foot switch, a further switching device, actuable manually with both hands, for the bowl control. This switching device is arranged on the pressing machine outside the laundry feed region. The loading of the bowl can take place only with the foot switch actuated and with the simultaneous actuation of the manual switching device. This additional safety measure prevents injuries to the fingers during the operation of the mangle, since the pressing operation can be initiated by means of the safety switch, as a result of the removal of the hands out of the laundry feed region, only after the laundry to be mangled has been inserted and smoothed.
